Subtitle: Ghost Monster (亡霊怪獣 Bōrei Kaijū ).
A disturbance from outer space had the Science Patrol investigate the matter to find themselves in the Monster Graveyard, where all aliens and monsters go when they are destroyed by Ultraman. Nearly all of them except a skeleton looking monster could be identified.
As they returned to Earth, the skeleton monster dubbed "Seabozu," fell from the sky and landed in a nearby city. As the Science Patrol was about to fire, they noticed that the monster wasn't intentionally attacking the city nor trying to harm anyone, but instead it climbed the tallest building in the city as if it were trying to get back into the sky... However after jumping off the building trying to jump into the sky, it fell to the ground below and wandered away whimpering. Finally, the Science Patrol cornered Seabozu in the middle of an open field away from society and opened fire upon the monster. After minutes of senseless violence and Seabozu being unrulingly attacked, it became obvious to the Science Patrol that Seabozu just wanted to go home to the Monster Graveyard.
The first attempt to send Seabozu home was to tie his hands around a massive rocket that would be sent to the Monster Graveyard. However the plan failed as Seabozu's weight and clumsiness caused the rocket to crash and burn on site. Ultraman showed up shortly afterwards and shockingly attacked the monster (possibly in hopes of knocking it out so he fly it home easier,) but Ultraman's color timer was running out and so he had to abandon Seabozu in mid-flight. Finally, a special rocket was designed for him. Ultraman met Seabozu again and ordered the monster to hold onto the rocket to take him home, but the monster's fear and stubbornness kept him from listening, provoking Ultraman at times to attack him into following his order. Finally after he grabbed onto the rocket. He was fired back to the Monster Graveyard where he could live the rest of his days in happiness.
His height is around 40 Meters tall. He weighs around 30,000 Tons.
